resolveFieldMessageCodes method

@override List<String> resolveFieldMessageCodes(String errorCode, String objectName, String field, Type? fieldType,)

The codes of an error of field of objectName with errorCode, most specific first. fieldType is the declared type of the field, null when unknown.

Implementation

@override
List<String> resolveFieldMessageCodes(
  String errorCode,
  String objectName,
  String field,
  Type? fieldType,
) {
  // Spring's algorithm: the field and its key-free forms qualified by
  // the object name, then unqualified plus the last path segment (and
  // its key-free forms), the field type and the bare code. A set drops
  // duplicates while keeping that order.
  final fields = _fieldList(field);
  final codes = <String>{
    for (final f in fields) _code(errorCode, '$objectName.$f'),
  };
  final dot = field.lastIndexOf('.');
  if (dot >= 0) {
    fields.addAll(_fieldList(field.substring(dot + 1)));
  }
  codes
    ..addAll([for (final f in fields) _code(errorCode, f)])
    ..addAll([
      if (fieldType != null) _code(errorCode, '$fieldType'),
      _code(errorCode, null),
    ]);
  return codes.toList();
}
